C++ program to display the diamond-like pattern using Inline function

Write a C++ program to display the diamond-like pattern using the Inline function.

C++ program to display the diamond-like pattern

The inline function inline int T4Tutorials::in() and inline int T4Tutorials:: T4Tutorials_Function() helps to increase the execution time of a program. The programmer can make a request to the compiler to make the inline function as inline int T4Tutorials::in() and inline int T4Tutorials:: T4Tutorials_Function().

Making inline means that compiler can replace the function definitions of inline int T4Tutorials::in() with the place where this function is called obj. in(); and obj. T4Tutorials_Function();.
The compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime.
